Campsis plant named ‘HOCH128’

ABSTRACT

A new and distinct cultivar of  Campsis  plant named ‘HOCH128’ is disclosed, characterized by red flowers, and long internodes. Plants are vining produce new flowers and flower buds throughout Summer. The new variety is a  Campsis , normally used for outdoor ornamental purposes.

Latin name of the genus and species: Campsis tagliabuana.

Variety denomination: ‘HOCH128’.

BACKGROUND OF THE INVENTION

The new Campsis cultivar is a product of a planned breeding programconducted by the inventor, in Moshav Bitzaron, Israel. The objective ofthe breeding program was to develop new Campsis plants for ornamentalpurposes. The cross resulting in this new variety was made duringSeptember of 2012.

The seed parent is an unnamed, unpatented proprietary variety of Campsistagliabuana. The pollen parent is a different unnamed, unpatentedproprietary variety of Campsis tagliabuana. The new variety was selectedin July of 2014 by the inventor in a group of seedlings resulting fromthe 2012 crossing, in a nursery in Moshav Bitzaron, Israel.

Asexual reproduction of the new cultivar was performed by graftedsoftwood cuttings. This was first performed at the same nursery inMoshav Bitzaron, Israel during January of 2015, and has shown that theunique features of this cultivar are stable and reproduced true to typein multiple successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘HOCH128’ has not been observed under all possibleenvironmental conditions. The phenotype may vary somewhat withvariations in environment such as temperature, day length, and lightintensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘HOCH128’ These characteristics incombination distinguish ‘HOCH128’ as a new and distinct Campsiscultivar:

-   -   1. Distinctive red flower color.    -   2. Long internodes.

PARENT COMPARISON

Plants of the new cultivar ‘HOCH128’ are similar to plants of the seedparent in most horticultural characteristics; however, plants of the newcultivar ‘HOCH128’ differ in the following;

-   -   1. The new variety has smaller flowers than the seed parent.    -   2. Flowers of the new variety are more open at the ends, less        cylindrical than flowers of the seed parent.    -   3. Plants of the new variety are not as compact as plants of the        seed parent.

Plants of the new cultivar ‘HOCH128’ are similar to plants of the pollenparent in most horticultural characteristics; however, plants of the newcultivar ‘HOCH128’ differ in the following;

-   -   1. The new variety has red flowers, while the pollen parent has        yellow flowers.    -   2. Plants of the new variety do not grow as vigorously as plants        of the pollen parent.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘HOCH128’ are comparable to the commercialvariety Campsis ‘Kudian’, U.S. Plant Pat. No. 13,139. The two Campsisvarieties are similar in most horticultural characteristics; however,the new variety ‘HOCH128’ differs in the following;

-   -   1. The new variety has red flowers; this comparator has orange        blooms.    -   2. Plants of the new variety are more compact than plants of        this comparator.

Plants of the new cultivar ‘HOCH128’ are comparable to the commercialvariety Campsis ‘Takarazuka Fresa’, U.S. Plant Pat. No. 23,917. The twoCampsis varieties are similar in most horticultural characteristics;however, the new variety ‘HOCH128’ differs in the following;

-   -   1. The new variety has longer flowers than flowers of this        comparator.    -   2. Plants of the new variety have longer internodes than plants        of this comparator, producing overall taller plants.    -   3. Plants of the new variety are not as compact as plants of        this comparator.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates a typical floweringplant of ‘HOCH128’ grown outdoors in Moshav Bitzaron, Israel atapproximately 1 year of age. FIG. 2 illustrates a close-up view offlowers of the new variety. The photographs were taken usingconventional techniques and although colors may appear different fromactual colors due to light reflectance it is as accurate as possible byconventional photographic techniques.
